BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates generally to a User Interface (UI) mode,and more particularly to a portable device and a method for providing aUI mode.

2. Description of the Related Art

Due to recent developments in technology, various portable devices, suchas smart phones, cellular phones, Portable Media Players (PMPs), etc.,receive input of user commands through a touch screen.

A capacitive touch screens have been primarily used for this purpose,which detects a touch point such that a charge field is spread over thesurface of the touch screen, and if a user's finger, which is a kind ofconductor, touches the charge field, the touch screen senses the chargepassing through the user's finger.

However, if a non-conductive object touches the capacitive screen, sucha touch is not recognized. Particularly, in a cold weather (such in acold countries including Russia, or in a ski area, for example), thetouch screen may be commonly operated by a gloved hand, and thecapacitive touch screen is unable to recognize such a gloved hand thatis not a conductor. Accordingly, despite the cold weather, a user mustpull off the gloves in order to operate the capacitive touch, which isinconvenient for the user.

In addition, in other cases where may be difficult to operate the touchscreen with a general touch operation, such as in the case where thehand is stained with foreign substances, in the case of driving a car,and in the case of taking a shower, it is necessary to operate theportable device without touching the touch screen.

Accordingly, there is a need for methods for operating the portabledevice through reception of an input of another user's motion other thantouch input.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION

Hereinafter, embodiments of the present invention are described indetail with reference to the accompanying drawings. It should be notedthat throughout the drawings, the same drawing reference numerals willbe construed to refer to the same elements, features and structures. Inaddition, descriptions of well-known functions and constructions may beomitted for clarity and conciseness.

FIG. 1 is a schematic block diagram illustrating the configuration of aportable device according to an embodiment of the present invention.

Referring to FIG. 1, a portable device 100 includes a sensor unit 110, adisplay unit 120, and a control unit 13. The portable device 100 may bea device that can perform a touch input through a touch screen, such asa smart phone, a cellular phone, a PMP, a tablet Personal Computer (PC),an Motion Picture experts' group audio layer-3 (MP3) device, etc.

The sensor unit 110 senses a user's motion to input a specified commandto the portable device 100. In this case, the sensor unit 110 includesat least one of a touch screen for sensing a touch input, a proximitysensor for sensing a proximity input, an acceleration sensor for sensingan acceleration change of the portable device 100, and a gyro sensor forsensing rotation of the portable device 100.

Specifically, the touch screen senses the touch input that is made by auser's direct touch of the screen with a user's finger. In presentexample, the touch screen may be a capacitive touch screen, but, otherstypes touch screen such as a resistive touch screen may also be used inaccordance with embodiments of the present invention. The portabledevice 100 can sense the touch input through a general touch screenoperation.

The proximity sensor senses the proximity input generated by a user'smovement over the screen in a state where a user's finger or an objectis spaced apart from the screen. Specifically, if the object or theuser's finger moves over the proximity sensor while being spaced apartfor a specified range, such as 1 to 3 cm, from the screen, the proximitysensor senses the proximity input.

An Infra-Red (IR) sensor may be used as the proximity sensor.Particularly, as illustrated in FIG. 2, IR sensors 210-1, 210-2, 210-3,and 210-4 may be provided at each corner of one surface of the portabledevice 100. Accordingly, the portable device 100 can sense the directionof the user's proximity input. For example, if the object moves from theIR sensor 210-1 that is provided at the left upper end to the directionof the IR sensor 210-2 that is provided at the right upper end, theportable device 100 recognizes that the proximity input in the rightdirection is sensed.

Further, three IR sensors may be provided at each corner in a mannerthat two of the three IR sensors emit an IR signal and one remaining IRsensor receives the reflected IR signal. Accordingly, the IR sensors cansense whether the object has moved over the sensors.

The above-described types of proximity sensors are merely provided asexamples, and different types of proximity sensors such as a RadioFrequency (RF) sensor may also be used in accordance with embodiments ofthe present invention. Similarly, the above-described positions of theproximity sensors are merely provided as examples, and proximity sensorsmay be positioned other position, such as at the center point of eachside of the portable device 100. Further, the number of areas in whichthe above-described proximity sensors are positioned, as well as thenumber of proximity sensors themselves, are merely provided as examples,and the proximity sensors may alternatively be provided in five or moreareas, for example, in accordance with embodiments of the presentinvention.

The acceleration sensor senses the change of acceleration of theportable device 100. Specifically, the acceleration sensor senses thedirection of the acceleration input by sensing the acceleration changethat occurs when a user shakes or hits the portable device 100. Forexample, if the user shakes the portable device 100 in the leftwarddirection or hits the left side surface of the portable device 100, theacceleration sensor senses the increase of the acceleration in the leftdirection. Accordingly, the portable device 100 can recognize that theacceleration input in the left direction has been sensed.

Further, the gyro sensor senses the rotation of the portable device 100.Specifically, the gyro sensor senses the rotation that occurs when theuser shakes or hits the portable device 100. At this time, the rotationdirection includes at least one of pitch, roll, and yaw directions ofthe portable device. For example, if the user shakes the portable device100 so that the left side surface of the portable device 100 is moveddownward, the gyro sensor senses that the portable device 100 is movedin the counterclockwise direction based on the roll direction of theportable device 100. Accordingly, the portable device 100 can recognizethat the rotation input in the left direction has been sensed.

As described above, the sensor unit 110 receives an input of the user'smotion through diverse sensors. However, the sensor unit 110 is notlimited to the above-described examples, and the user's motion may besensed by another sensor such as a geomagnetic sensor in accordance withembodiments of the present invention.

The display unit 120 displays various kinds of mode screens under thecontrol of the control unit 130. For example, the display unit 120 candisplay a standby mode screen that corresponds to a state where the userdoes not use the portable device. Further, in accordance with the typeof motion input by the user, the display unit 120 can display one of atouch UI mode that operates according to the touch input, a proximity UImode that is operated by the proximity input, an acceleration UI modethat operates according to the acceleration input, and a rotation UImode that operates according to the rotation input.

The control unit 130 controls functions of the portable device 100 inaccordance with the user's motion input by the sensor unit 110.

Specifically, if a specified user's motion is sensed by the sensor unit110, the control unit 130 controls the display unit 120 to release thestandby mode of the portable device 100 and to output a UI mode screenthat corresponds to the type of the user's motion. In this case, thecontrol unit 130 provides at least one mode selected from among thetouch UI mode, the proximity UI mode, the acceleration UI mode, and therotation UI mode in accordance with the type of the motion input by theuser.

Hereinafter, with reference to FIGS. 3A to 5, a method of providing a UImode according to the type of motion input by the user is described.

FIGS. 3A and 3B are diagrams illustrating a touch UI mode in accordancewith a touch input according to an embodiment of the present invention.Generally, if the user does not use the portable device 100, the screenof the portable device 100 is in an off state. If a specified buttonthat is provided on the outside of the portable device 100 is pressed,the portable device 100 provides a standby mode screen. In this case,the “standby mode screen” refers to a screen on which a menu forexecuting a specified application is not displayed, but only simpleinformation such as date and time is displayed.

In the standby mode screen state, an icon 310 is displayed on the touchscreen of the portable device as illustrated in FIG. 3A. In this case,if the user touches and moves the icon 310 to a specified area, thecontrol unit 130 releases the standby mode of the portable device 100and provides a touch UI mode. Further, the control unit 130 controls thedisplay unit 120 to convert the standby mode screen into the touch UImode screen and to display the touch UI mode screen as illustrated inFIG. 3B.

Herein, the term “touch UI mode” refers to a mode for performing thefunction of the portable device 100 through the sensing of the user'stouch input through the touch screen. Accordingly, the control unit 130controls the portable device 100 using the touch input sensed by thetouch screen. The touch UI mode screen provides general functions of theportable device 100 as well as diverse application menus. For example,as illustrated in FIG. 2B, the touch UI mode screen provides menus forproviding the basic functions of the portable device 100 (e.g., a phonemenu, a photo menu, a text menu, etc.), as well as menus for providingapplication functions such as an E-book application, a news application,a stock application, a game application, and an Internet application.

As described above, the standby mode can be released by moving the icon310 to a specified area. However, the standby mode can also be releasedby other methods in accordance with embodiments of the presentinvention. For example, the standby mode can be released by anothermethod using the touch screen such as inputting of a password throughthe touch screen.

FIGS. 4A and 4B are diagrams illustrating a proximity UI mode inaccordance with a proximity input according to an embodiment of thepresent invention.

In the standby mode state as described above with reference to FIG. 3A,the user performs the proximity input while being spaced 1 to 3 cm fromthe touch screen. More specifically, as illustrated in FIG. 4A, if auser's hand makes one round trip from left to right and back to left (orvice versa) while being spaced apart from the touch screen, the controlunit 130 senses the user's proximity input through the proximity sensor,and as illustrated in FIG. 3B, controls the display unit 120 to displaya screen to which an effect of removing the standby mode screen upwardis applied. Then, if the user's hand makes another round trip in theleft and right directions, the control unit 130 controls the displayunit 120 to display a screen to which an effect of removing the standbymode screen as illustrated in FIG. 4B further upward is applied asillustrated in FIG. 4C. Then, if the user's hand makes still anotherround trip in the left and right directions, the control unit 130controls the display unit 120 to display the proximity UI mode screen asillustrated in FIG. 4D.

In this case, the control unit 130 provides the proximity UI mode screenonly when continuous proximity input (i.e., the left/right round trip)has been performed three times. Specifically, if the proximity input inthe left and right directions is not sensed within a specified time (forexample, 2 seconds) after a first proximity input in the left and rightdirections is made, the control unit 130 provides the display screen inthe previous step. For example, if the proximity input in the left andright directions is not sensed within two seconds in a state where thetwo times proximity input in the left and right directions are sensedand the screen as illustrated in FIG. 4C is displayed on the screen, thecontrol unit 130 controls the display unit 120 to converts the screen asillustrated in FIG. 4C into the screen as illustrated in FIG. 4B.Further, the control unit 130 releases the standby mode and provides theproximity UI mode only when the proximity input in the left and rightdirections is performed twice in a state where the screen as illustratedin FIG. 4B is displayed on the screen.

As described above, through the three continuous proximity inputs in theleft and right directions, the control unit 130 releases the standbymode and provides the proximity UI mode.

Herein, the term “proximity UI mode” refers to a mode in which theproximity input according to the user's movement, which is spaced apartfrom the touch screen, is sensed and the function of the portable device100 is performed. Accordingly, the control unit 130 controls theportable device 100 using the proximity input sensed by the proximitysensor. Hereinafter, with reference to FIG. 5, the proximity inputaccording to the user's action and a method of controlling the portabledevice 100 accordingly is described.

As illustrated first on the left side of FIG. 5, “up/down sweeping”refers to the movement of the user's hand in the upward and downwarddirections relative to the touch screen. Specifically, the “up sweeping”refers to the movement of the user's hand from the lower surface of thetouch screen to the upper surface thereof. If the up sweeping action isinput, the control unit 130 performs an action such as an actioncorresponding to a “▴” button for converting the menu display in theupward direction. The “down sweeping” refers to the movement of theuser's hand from the upper surface of the touch screen to the lowersurface thereof. If the down sweeping action is input, the control unit130 performs an action such as an action corresponding to a “▾” buttonfor converting the menu display in the downward direction.

As illustrated second in FIG. 5, “left/right sweeping” refers to themovement of the user's hand in the left and right directions relative tothe touch screen. Specifically, the “left sweeping” refers to themovement of the user's hand from the right surface of the touch screento the left surface thereof. If the left sweeping action is input, thecontrol unit 130 performs an action such as an action corresponding to a“

” button for converting the menu display in the left direction. The“right sweeping” refers to the movement of the user's hand from the leftsurface of the touch screen to the right surface thereof. If the rightsweeping action is input, the control unit 130 performs an action suchas an action corresponding to a “

” button for converting the menu display in the right direction.

As illustrated third in FIG. 5, “cover” refers a movement covering thewhole touch screen. If the cover action is input over a specified time,the control unit 130 operates to finish the proximity UI mode and toturn off the screen of the display unit 120.

As illustrated fourth in FIG. 5, “space tap” refers a movement for ashort time from upper to lower positions in the screen direction of thetouch screen or a movement for a short time from lower to upperpositions in the screen direction of the touch screen.

As illustrated fifth in FIG. 5, if the hover action is input, thecontrol unit 130 performs a function of adjusting a volume of theportable device 100. For example, if the hover action slowly moving fromupper to lower positions is input, the control unit 130 lowers thevolume of the portable device 100. If the hover action slowly movingfrom lower to upper positions is input, the control unit 130 raises thevolume of the portable device 100.

As described herein with reference to FIG. 5, various actions accordingto the proximity input correspond to operations such as menu displayconversion, and selection, cancellation. However, these movement actionsand corresponding operations are merely provided as examples, andvarious other actions according to the proximity input may be performedto correspond to the respective menus in accordance with embodiments ofthe present invention.

Specifically, if the motion is performed in a first direction, thecontrol unit 130 selects the first menu and performs a function thatcorresponds to the first menu, and if the motion is performed in asecond direction, the control unit 130 selects the second menu andperforms a function that corresponds to the second menu. For example, ifthe left sweeping action is input, the control unit 130 selects a phonecall menu to perform a call function, and if the right sweep action isinput, the control unit 130 selects a photographing menu to perform aphotographing function.

Next, for the proximity UI mode, the proximity UI mode screen displays amenu for a general function such as a phone call menu and a text menuprovided by the portable device 100. In this case, the proximity UI modescreen can provide menus the number of which is smaller than the numberof menus provided by the touch UI mode screen, because when theproximity UI mode, the input method is limited in comparison to theinput method of the touch UI mode, and thus it is necessary to displaymenus for essential functions.

The proximity UI mode screen also provides the menu arrangement and menusize, which are different from those of the touch UI mode screen. Forexample, as illustrated in FIGS. 3B and 4D, the proximity UI mode screenmay be larger than the menu that is provided on the touch UI modescreen. Further, on the proximity UI mode screen, menus are arrangedonly in the left and right directions, whereas on the touch UI modescreen, menus can be arranged in all directions, that is, in up, down,left, and right directions.

In addition to the touch UI mode and the proximity UI mode as describedabove with reference to FIGS. 3A to 5, the portable device can providean acceleration UI mode and a rotation UI mode. Specifically, if theportable device 100 is shaken three times in a standby mode screenstate, the control unit 130 releases the standby mode and provides theacceleration UI mode. In this case, the acceleration UI mode means amode in which the acceleration input according to the accelerationsensor is sensed and the portable device 100 is controlled accordingly.

Further, if the portable device 100 is rotated three times in the leftand right directions, based on the roll direction of the portable device100 in the standby mode screen state, the control unit 130 releases thestandby mode and provides the rotation UI mode. In this case, therotation UI mode refers to a mode in which the rotation input accordingto the gyro sensor is sensed and the portable device 100 is controlledaccordingly.

As described above, by providing diverse modes according to the type ofthe motion, the portable device 100 can be controlled even in the casewhere the capacitive touch screen is unable to be used due to climaticconditions or specified circumstances.

Referring back to the control unit 130 of FIG. 1, if a specified commandis input in another UI mode except for the touch UI mode, the controlunit 130 operates to convert the other UI mode into the touch UI mode.For example, if a touch UI mode conversion icon is selected in theproximity UI mode, the control unit 130 may operate to convert theproximity UI mode into the touch IO mode. Further, if a mode conversionbutton provided on the case of the portable device 100 is pressed, thecontrol unit 130 may convert the proximity UI mode into the touch UImode.

FIG. 6 is a flowchart illustrating a method of providing a UI mode of aportable device according to an embodiment of the present invention.

Referring to FIG. 6, a method of providing a UI mode of a portabledevice 100 is described as follows. First, the portable device 100senses the user's motion using the sensor unit 110, in step S605. If theuser's motion is sensed, the portable device 100 confirms whether thesensed motion is a touch input, in step S610. If the sensed motion isdetermined to be the touch input in step S610), the portable device 100determines whether the input motion is a standby mode release motion, instep S620. Specifically, the portable device 100 determines whether theinput motion is a motion that moves the icon 310 displayed on the touchscreen, which corresponds to the standby mode release motion by thetouch input, to the specified area.

If the motion input to the portable device 100 is determined to be thestandby mode release motion by the touch input in step S620, theportable device outputs the touch UI mode screen, in step S625. Then,the portable device 100 converts the present mode into the touch UImode, and performs the function of the portable device 100 according tothe touch input, in step S630.

However, upon a determination that the motion input to the portabledevice 100 is not the touch input in step S610, and the proximity inputis performed in step S615, the portable device 100 determines whetherthe input motion is the standby mode release motion according to theproximity input, in step S635. Specifically, the portable device 100determines whether the input motion is a motion that including threeround trips in the left and right directions while being spaced apartfrom the touch screen, which is defined as the standby mode releasemotion according to the proximity input.

If the motion input to the portable device 100 is determined to be thestandby mode release motion according to the proximity input in stepS635, the portable device 100 outputs the proximity UI mode screen instep S640. In this case, the number of proximity UI mode screens may beless than the number of menus that are displayed on the touch UI modescreen, and the size and arrangement of the proximity UI mode screen maybe different from the size and arrangement of the menu that is displayedon the touch UI mode screen.

While the proximity UI mode screen is displayed, the portable device 100determines whether there is an input for changing the present mode tothe touch UI mode, in step S645. Specifically, the portable device 100determines whether a touch UI mode change icon that is displayed on theproximity UI mode screen or a touch UI mode change button that ispositioned on the outside of the case of the portable device 100, anddetermines whether to change the proximity UI mode to the touch UI mode.

At this time, if an input for changing the present mode to the touch UImode is received in step S645, the portable device 100 outputs the touchUI mode screen in step S625, and perform the function of the portabledevice by the touch input in step S630.

However, if no input for changing the present mode to the touch UI modeis received in step S645, the portable device 100 performs the functionof the portable device by the proximity input in step S650.

In the method according to FIG. 6, it is assumed that the portabledevice 100 provides the touch UI mode and the proximity UI mode.However, the portable device 100 may further provide other UI modes suchas the acceleration UI mode and the rotation UI mode except for thetouch UI mode and the proximity UI mode.

As described above, according to embodiments of the present invention, aportable device can be controlled even when the touch screen is unableto be used due to climatic conditions or other specified circumstances.
